Put oil
into skillet and heat, add pressed garlic, bell pepper and onion and 1/2 of the
oregano leaves. Cook and stir 3 to 4 minutes or until vegetables are
crisp-tender. Remove pan from heat, unroll 1 pizza crust onto lightly floured
surface, with the dough and pizza roller, roll out crusts to a 12 X 9 rectangle;
cover with half of the cheese, beef and vegetable mixture to within 1/2 inch of
edges of dough.

Starting at longest side of rectangle, roll up dough, jelly roll
fashion. Press seam together to seal. Repeat with remaining crust and filling
ingredients. Place rolls seam down on the 15" round baking stone. Join ends of
rolls together to form one large ring. Press ends together to seal. In small
bowl, combine egg white and water, brush onto dough using a pastry brush.
Sprinkle the remaining 1/2 tsp. oregano on top of ring.
